A decidedly fiercer look than the flirty, feminine frocks we've come to expect from Bosworth, this backless beauty is a shining example of the new minimalism done right. Though her Isabel Marant heels are not exactly suited for the Sundance snow, we can't help but pine for a pair. The cutaway back and peekaboo midriff rev up this otherwise basic black dress, and the killer heels keep it edgy and modern.
